> Right now, operations like {{collect()}} and {{take()}} can crash the driver with an OOM if they bring back too many data. We should add a {{spark.driver.maxResultSize}} setting (or something like that) that will make the driver abort a job if its result is too big. We can set it to some fraction of the driver's memory by default, or to something like 100 MB.
